i updates the link to the right question

You'll use the combinations formula as the numbers do not have to be in a specific order. For each slot, 9 numbers could go there (slot 1 could have 1,2,3,4,5,6,7,8,or9... etc)
In your formula, n is the number of things you can choose from, and r is how many you choose. Then you can just substitute and solve =)

Coll Do you have skype so i can talk to you to solve this

- anonymous

No, I don't. I'm sorry =(

So what do you mean by examples 0 and 1?

- anonymous

For that they want me to put for 0,1,2,3,4,5,6,7,8,9
For 0 i put 9 and 1 i put 8 and 2 i put 7?

- anonymous

I don't quite understand, but from what I do get I don't think you're on the right track.
All you should need to do is figure out what 'n' and what 'r' is.

- anonymous

my heads about to blow from this question And Would N Be 3?

- anonymous

You know what, I am so sorry but I was wrong. Because each slot can only be occupied by one number, it is actually a permutation. Very sorry! So it is the same process, but the other formula.
To find N, how many numbers are available for you to choose from?

- anonymous

i can pick any number for 0-9 for n and r so all i gotta do is 10x9x8x7x6x5x4x3x2x1

- anonymous

which is B

- anonymous

I don't think it's B. You are correct that N is going to be 10, but then you have to also plug it into the formula.

- anonymous

C

- anonymous

3628800

- anonymous

Yes, it will be C. =) Good job!! Sorry I probably wasn't the most helpful
